Iceface 2.0 commandLink 部分提交不起作用

我有一个页面，它接受地点的请求参数，然后生成信息，例如，http://example.com/xxx/weather.jsf?place=california。这样做的目的是让用户为链接添加书签。

在weather.jsf 中，有两个输出文本和一个命令链接：

Humidity : <ice:outputText value="#{weatherBean.humidity}"/>
Visibility : <ice:outputText value="#{weatherBean.visibility}"/>
<ice:commandLink id="likeButton" 
  value="Like"
  actionListener="#{weatherBean.doLike}" />

在managementBean 中：

@ManagedBean(name="weatherBean")
@RequestScoped
public class WeatherBean
{
 String humidity;
 String visibility;
 int numLike; 

 @PostConstruct
     public void init()
 {
  System.out.println("init called");
  HttpServletRequest request= (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
  String place = request.getParameter("place");
  setHumidity(WeatherDao.getHumidity(place));
  setVisibility(WeatherDao.getVisibility(place));
  setNumLike(GeneralDao.getNumLike());
 }

 public void doLike(ActionEvent event)
 {
  System.out.println("doLike called");
  GeneralDao.addNumberLike();
 }
}

好的，页面生成得很完美。但是，当我单击 doLike commandLink 时，它总是先触发 init 方法，然后调用 doLike 方法。由于请求参数为空，所有其他值都会重置。有什么方法可以防止刷新页面或调用 init 方法吗？我尝试了部分提交或立即提交，但没有运气。

原文

I have a page which takes in request params for place, then generate information,
for example, http://example.com/xxx/weather.jsf?place=california.
The purpose of doing this is to let user bookmark the link.

In the weather.jsf, there are two outputtext and a commandlink:

Humidity : <ice:outputText value="#{weatherBean.humidity}"/>
Visibility : <ice:outputText value="#{weatherBean.visibility}"/>
<ice:commandLink id="likeButton" 
  value="Like"
  actionListener="#{weatherBean.doLike}" />

In the managedBean:

@ManagedBean(name="weatherBean")
@RequestScoped
public class WeatherBean
{
 String humidity;
 String visibility;
 int numLike; 

 @PostConstruct
     public void init()
 {
  System.out.println("init called");
  HttpServletRequest request= (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
  String place = request.getParameter("place");
  setHumidity(WeatherDao.getHumidity(place));
  setVisibility(WeatherDao.getVisibility(place));
  setNumLike(GeneralDao.getNumLike());
 }

 public void doLike(ActionEvent event)
 {
  System.out.println("doLike called");
  GeneralDao.addNumberLike();
 }
}

Alright, the page generated perfectly.
However, when I click the doLike commandLink,
it always triggers the init method first, then call doLike method.
Since the request param is empty, all the other values reset.
Is there any way to prevent a refresh of the page or calling of init method?
I tried partialsubmit or immediate, but no luck.
